How Subscription Filters Work

Every family and home has different air quality demands, which is why we offer to give you a new filter whenever you may need one without trying to upsell you with extra unnecessary filters.

Once your filter has been exhausted (changes to yellow), if you are subscribed to the monthly subscription, simply tweet or e-mail us (veronica@serionix.com) a picture and we'll send you a fresh new filter right away (as frequently as 1 a month). If your filter doesn't change color after 4 months or if we haven't heard from you, we'll send you a fresh filter automatically. If you are unhappy with our filters you can cancel at any time after the first 2 months and we'll refund you in full.
